Magnetic suspension paddle distance self-adjusting vertical shaft wind power generator

Abstract

The invention discloses a magnetic-suspension vertical shaft self-conditioned pitch aerogenerator which comprises a magnetic-suspension aerogenerator. A generator shaft of the magnetic-suspension aerogenerator and an impeller shaft of an impeller are integrally made. The generator shaft on which a rotor of the generator is arranged is penetrated into a motor casing on which a generator unit stator is arranged, and an axial magnetic suspension device and a radial magnetic suspension device are arranged on the generator shaft and in the motor casing for magnetic suspension positioning; the impeller shaft is arranged in a wheel hub fixedly and a plurality of blades of the impeller are connected with the wheel hub through the self-conditioned pitch device of the vertical shaft. The aerogenerator has advantages of simple structure and convenient use, effectively improves the whole performance of the aerogenerator, enhances efficiency, has energy saving, consumption reduction and environmental protection and is easy for popularization, etc.

Description

technical field

[0001] The invention relates to a wind power generator, in particular to a magnetic levitation self-adjusting pitch vertical axis wind power generator. Background technique

[0002] Wind turbines are classified according to the direction of the rotation axis, which can be divided into two types: horizontal axis and vertical axis. Horizontal axis wind turbines are developed and matured theoretically based on aircraft propellers, and are currently widely used. However, the design and manufacture of horizontal axis wind turbines are very complicated, and have: 1. The impeller occupies a large space and covers an area; 2. The requirements for the wind tower are high; 3. The impeller is not uniformly winded, especially the ones installed in the air The blades must also bear the huge positive pressure of the wind, so their cost is very high. The greater the power of a single machine, the greater its cost. This is one of the main factors why the price of wind power...
